Hi Joyceyoungreality,

unfortunately not. At the moment, in the Blog module there is a tight coupling between user accounts and parent blogs: an user account can own one only parent blog, and vice versa one parent blog can have one only owner, there's a biunivocal relationship between them. In this scenario, child blogs are managed as sub-blogs or categories: this means that they are all owned by their parent blog's owner. This is one of the biggest limit of the module, that will be eliminated in the next version that will be rewritten from the ground up.

Best regards,
Dario Rossa
